Conceptual Architecture

FIG. 1 is a diagram illustrating an exemplary concept FIGS. 1A, 1B of a multifunctional light bulb structure 100, according to one aspect, illustrating all parts 150, 160 of an assembled light bulb with 150 illustrating an aerial view of an assembled light bulb. According to the aspect 160, a light bulb lamp 101 may comprise a generally dome-type bulb having solid walls (generally forming an A-shape frame, however it should be appreciated that other final lamp shapes may be used according to a desired arrangement or use case, such as using a spiral lamp shape or a candle lamp shape, or other shape) formed of solid, opaque or either fully or partially translucent or transparent material such as metal or plastic, and configured to enclose a light source (FIG. 10) within lamp 101 when assembled; and configured to contain cut-out spaces 106 a-n for various arrangements and configurations of sensors, ports, signals, or buttons (it should be appreciated that other ports such as a Micro-DVI, HDMI, or other port types may be used according to a desired arrangement or use case, and that the physical arrangement of ports may vary) to control enclosed light source (FIG. 10). Lamp 101 is configured for cut-out spaces 106 a-n for sensors such as an ambient light sensor for multifunction modes (FIG. 13), ports such as USB for connecting to a system for charging or other uses, signals such as to indicate that charging is in progress or complete, and buttons such as could be used for mode or power selection, for example to select different brightness or color settings, strobe effects or other pulse or interval-based lighting behaviors, or to alter the polarity of connectors to external power to accommodate various light bulb sockets that may be encountered. It should be appreciated that other ports such as Micro-DVI, HDMI, or other port types may be used according to a desired arrangement or use case; as it should also be appreciated that other signals may be used such as low battery signal or other signal may be used according to a desired arrangement or use case, and that the physical arrangement of such features may vary).

Further according to the aspect, a lamp cover 102 may comprise a generally rounded shape having semi-translucent or translucent walls formed of a material such as glass or plastic, and configured to fit on top of lamp 101 to further enclose light source (FIG. 10). Attached to base of lamp 101 is locking mechanism 103, formed of a solid material such as metal or plastic (it should be appreciated that other bases for a light bulb lamp such as a heatsink or ballast housing may be used according to a desired arrangement or use case). Extendable bulb neck 105 runs through center of locking mechanism 103 and lamp 101; bulb neck 105 may comprise a generally tubular shape having solid walls formed of a material such as plastic with a threaded base for attaching to screw cap base 104. Screw cap base 104 may comprise generally tubular shape sealed at one end and containing threads, having solid walls formed of a material such as metal (generally forming an E27 Edison screw, however it should be appreciated that other final screw cap bases may be used according to a desired arrangement or use case, such as an E26 Medium Edison Screw (MES) or a BA22d Bayonet Mount cap (BC), or other screw cap base). Also according to the aspect 150, aerial view of assembled light bulb 100 shows buttons 106 a-n are raised from lamp 101 for an easier use case (it should be appreciated that buttons may be level with lamp body according to a desired arrangement or use case). Lamp cover 110 attaches to lamp, allowing light transmission through top of bulb 111.

Materials used, and arrangements thereof, in the construction of a multifunctional solid-state light bulb 100 may be selected and configured in such a way as to be flame, dust, shock, or water-resistant to various standardized protocols, according to a particular arrangement or use case. For example, materials may be selected that are flame-retardant and electrically-insulating by nature, and construction may be configured to include seals or tight tolerances in various key areas to prevent the ingress of dust or water.

FIG. 2 is a diagram illustrating an exemplary light bulb neck extension 200, illustrating a flashlight function of the light bulb, according to one aspect. According to the aspect, locking mechanism 201 moves along bulb neck 202 to extend bulb to desired length for use as a flashlight. Extendable bulb neck 202 attaches to screw cap base 203 allowing for an extended bulb in a lamp or wall socket. According to various arrangements or configurations, neck extension 200 may be used to optionally cover or reveal buttons, ports, or other features 106 a-n, for example so that when bulb neck extension 200 is in a retracted or closed position, the general shape and appearance of the bulb 100 is that of a traditional light bulb without noticeable external features (as may be suitable for closely fitting in specific types of sockets, or in close spaces originally designed for standard light bulbs), and then by extending or opening bulb neck extension 200, the ports, buttons, and other features 106 a-n may be revealed while simultaneously forming an extended handle or grip for use as a flashlight, placing the now-exposed controls in a suitable location for manual operation while using the bulb 100 as a flashlight. In this manner, bulb 100 may be configured to be suitable in use cases designed to accommodate traditional light bulbs without compromising functionality, while also being configured to provide a suitably convenient flashlight mode of operation by extending the bulb neck extension 200 when desired.

FIG. 15 is a diagram illustrating an abstraction of an exemplary power management circuit arrangement that may be used in the operation of a multifunctional solid-state light bulb, according to one aspect. According to the aspect, a power switching circuit 1501 may be used to select between an internal power source such as a battery 1510 and an external power supply 1520 such as a light bulb socket or power outlet. Power switching may be directed automatically by a power detection circuit 1502 that may detect external power connections and select external power 1520 when available, falling back to internal power 1510 when external power is unavailable, or power switching may be performed manually using a button 1503 to select a power source. For example, more than one power source may be connected at a time, and a user may manually select which power to use via a clickable button or toggle 1503, for example in some arrangements that may use internal and external power that provides different voltages, which may affect the light produced by a light emitter 1530 used in the solid-state bulb. For example, some handheld flashlights in the art may use multiple types of internal replaceable battery for power, with the voltage of the battery used affecting the brightness of the light output, giving users the option of using high-performance batteries such as 3-volt or higher lithium batteries for brighter light, or more commonly-available low-voltage alkaline batteries (commonly around 1.5 volts) for the sake of availability. Another use for button 1503 may be to select the polarity or other behavior of an external power connection 1520, for example to accommodate light bulb sockets that may have the leads connected in a different order or to accommodate international travel where external power connections may adhere to differing standards.

FIG. 16 is a diagram illustrating an abstraction of an exemplary mode management circuit arrangement that may be used in the operation of a multifunctional solid-state light bulb, according to one aspect. According to the aspect, a physical button 1601 may be used to control the operating mode of a multifunctional solid-state light bulb, for example by allowing a user to press button 1601 a number of times in series as detected by a counting circuit 1602 to select an operating mode (as described previously, with reference to FIGS. 11-14). For example, a number of presses may be detected by click counter 1602 and used to trigger a strobe modulation circuit 1603 to direct a light emitter 1604 to operate in a pulsing, flashing, or other output pattern, for example by modulating the input from a power source 1606. Additionally, a series or combination of presses may be used to trigger an audible alarm using an audio emitter 1605, for example to trigger an emergency mode with an audible alarm and a flashing light pattern such as to signal “SOS” via Morse code, as described in FIG. 12. In this manner, various patterns and combinations of short, long, or repeated activations of button 1601 may be used to select various visual and audible operations of a multifunctional solid-state light bulb, according to various configurations.
